>> Rotorless Rheometer MFR 100Lite
|
|
Brief Descriptions:
|
|
Rotorless Rheometer MFR 100Lite is a newly-designed, in compliance with ASTM D5289, for testing the visco-elastic properties of rubber compounds. It's equipped with the latest temperature control system, advanced temperature probe and precise torque transducer as well as strict quality control in manufacture, which ensure MFR100Lite possessing excellent repeatability, reproducibility and sensitivity at the top level worldwide. Together with incorporating friendly graphical interfaces, powerful data processing capacity, and strong network function, it greatly improves users' testing capability, facility and efficiency.

|
|
|
S'—Elastic Torque; S"— Viscous Torque; TanDelta(Hysteresis Loss)—S"/S';
TC90 —90% Cure Time; TC50— 50% Cure Time;
ML— Minimum Torque; MH— Maximum Torque;
TS1— Scorch Time (time for 1 torque unit after ML); TS2— Scorch Time (time for 2 torque units after ML)
